Measurement of Large-Scale Cluster Power Characteristics for Geometric Channel Models

Directional urban radio channel measurements are analyzed in this paper. The mean powers, the shadow fading, and the lifetimes of individual propagation clusters extracted from the measured data are studied. The cluster shadow fading is an input parameter of several directional channel models, but measured values for the fading have not been published previously. Also, measured numbers of strong, significant propagation clusters are essential for the channel models.
